I'm switching from Raspberry PI 3 to Rock64. Received my unit yesterday.https://www.pine64.org/?page_id=7147
It's way more powerful and has 1gb LAN that actually works (1gb up and down on NAND and 500down/1000up on my old HDD.
The problem is, it's arm64 not armhf.
I installed Ubuntu Xenial armhf but LAN speed drops in half.
Is there any possibility to install GIMX on Debian Stretch with arm64 architecture?

I know there is no official support and I don't require one. Just ability to install it and test if it works or not.
